Mike Pence knows he's going to be forced to speak to the Jan. 6 grand jury: aides

Former Vice President Mike Pence has tried to dodge a subpoena around the special counsel's investigation of the Jan. 6 attacks on Congress and the attempt to overthrow the election.

He's claiming that as the president of the Senate, he was operating in his role as a legislator, thus he should be safe from testifying due to Article 1, Section 6 of the U.S. Constitution, the "speech and debate clause." It protects lawmakers who are working in the course of their jobs as an elected official.
